JOHN JOSEPH KELLY, OF NORTH CAMBRJDGE, MASSACHUSETTS.

RAILROAD TIE.

Application filed August 13, 1921,

To all whom it may concern:

Be it known that I, JOHN JOSEPH KELLY, a citizen of the li nited States, residing at 2508 Massachusetts Avenue, North (lambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in a Railroad Tic; and I do hereby declare. the following to be a full, clear, and exact description of the iuvention, such will enable other skilled in the art to which it appertains to make and use the same.

This invention comprehends broadly, improvements in railroad ties and has particular reference to devices of such a character as is adapted to be connected with steel rails such as are used on steam and electric railroads.

As a principal object, this invention contemplates the provision of a concrete railroad tie which shall be readily adjusted to a steel rail or other material of hard substance in such a manner as to withstand the strain of carrying a heavy train of cars being run over the said steel rail without the vibration usually caused by a heavy train of cars running over a steel rail laid on a hard substance.

A further object is the provision of a concrete railroad tie which is constructed with such regard to proportion both with regard to the number and arrangement of its parts as to be cheaply manufactured and will also be durable and efiicient in operation and may readily be imbedded in the road bed of any railroad system with minimum expense of time and labor.

An object of equal importance with the foregoing, is to provide a concrete tie which shall be of suflicient strength as to be capable of bearing heavy weights and standing the strain of heavy loads either of heavy railroad trains or heavy machinery.

The above and additional objects are accomplished by means as are illustrated in the accompanying drawings and described in the following specifications and are more particularly pointed out in the claim which is appended hereto and forms a part of this application.

With reference to the drawings wherein I have illustrated the component parts of my invention and throughout the several views of which, like characters of reference designate similar parts.

Figure 1 is a view of a portion of a con- Serial No. 492,149.

crete tie as adjusted to the steel rail as it wi ll appear in actual use.

Figure 2 is a perspective of one section of my concrete tie showing top and bottom view of the resilient plate shown in Figure l.

Proceeding now to the description of the drawings, having particular reference to the disclosures of Figure l. The numeral (1) designates the upper portion of my concrete tie as sunk in the ground connected to a steel rail, the said steel rail 2 resting on easement plate 3 which is attached to steel rail 2 by means of clips 1 attached to easement plate 3 by bolts 5. The said bolts 5 attaching clips 4 extend through the top of easement plate 3 and are fastened to easement plate 3 by means of nuts 6.

The number 8 designates tie bolt which is imbedded in the concrete tie shown in F igure 1. These tie bolts 8 are imbedded in the concrete tie and fasten easement plate 3 to the concrete tie 1 by nuts 9.

As shown in the drawings, the concrete tie l, is furnished with a tie plate 10, resting thereon, an easement plate 3 resting on said tie plate 10, said easement plate and tie plate being apertured at 11 through which apertures bolts 8 are inserted, the said bolts 8 being firmly imbedded in the concrete tie 1 and with nuts 9 screwed thereon hold said tie plate and said easement plate firmly on said concrete tie; the said easement plate 3 is apertured also at 12 and is furnished with clips 4. which are also apertured; the said bolts 5 are inserted through said apertures in the said clips and said easement plate and with nuts 6 screwed thereon hold the said easement plate 3 securely to the steel rail 3 as illustrated in the accompanying drawings, thereby providing a durable railroad tie of hard substance and preventing Vibration usually caused by trains running on a steel rail laid on a hard substance.

Although in the foregoing I have illustrated in the drawings and described in the specifications such combination and arrangement of parts of my concrete tie and easement plate as constitute the preferred embodiment of my invention and the principal adaptations of the use thereof, I desire to emphasize the fact that I may make such minor changes in the matters of proportion and degree in my concrete tie and easement plate as shall not alter the spirit of my invention as defined in the appended claim.

I claim:
